Specification of Letters Patent.

Patented Aug. 23, 1921.

To all whom it may concern:

Be it known that L-Jorm WALDHEIM, a citizen of the United States, residin in Elizabeth, in the county of Union and tate of New Jersey, have invented certain new and useful Improvements in Typewriting- Machines, of which the following is a specification.

This invention relates to typewriting machines, and more particularly to means for collating work-sheets of various sizes in various relative positions prior to typing on the collated sheets.

The present invention is shown applied in one form to an Underwood typewriting machine, and may comprise a collating board or table pivotally mounted upon a rod secured to the typewriter carriage, and which may be swung from a sheet-delivering position behind the platen to a forward or collating position where the work-sheets may be collated thereon.

The work-sheets may be collated relatively to each other by indices' on the collating table and corresponding indices on the work-sheets, and may be held on said table by spring-controlled flaps which are hinged on said table so that they may be swung away therefrom during the sheet-collating operation.

The collating table, after the work-sheets have been adjusted thereon, is movedto a position back of the platen, so that the worksheets thereon may be conveniently fed forward therefrom and introduced around said platen. To introduce the work-sheets around the platen, there are preferably mounted on the collating table feed-rolls, which may be of which is curved upwardly and forwardly to guide downwardly the leading ends of the work-sheets if they extend a considerable distance beyond the end of the collating table, with the result that the ends are directed downwardly toward the platen while the sheets are being collated on said table.

Other features and advahtages will hereinafter appear.-

In the accompanying drawings,

Figure 1 is a perspective view, showing the invention applied to the typewriter carriage, and the collating table swung to its collating position.

Fig. 2 is a sectional side elevation, showing parts in their normal writing posi ion, and a work-sheet extending from the collating table around the platen.

.Fi .3 is a view similar to Fig. 2, but showing t e collating table swung to its collatin position, and the platen feed-rolls release Fig. 4 is a front elevation of Fig. 2, the upper part of the collating table being broken away.

the types upon type-bars 14. The platen may be rotatedafter each'line has been written by the usual ."line-spacing mechanism comprising a linek'space handle 15, which,

manipulated by means of a finger-piece until awhen operated, moves a slide 16 carried the first writing line upon the work-sheets appears at the usual wing-scales at the front of the platen with reference to which the work-sheets may be accurately adjusted if necessary. Auxiliary'to the collating table feed-rolls,the usual platen feed-rolls, which ordinarily cooperate with the typewriter platen, are provided and are automatically released when the collating table is moved to collating position. These platen feed-rolls are rendered effective by a finger-piece after the work-sheets have been adjusted around said platen, so that the work-sheets may then be line-spaced by the .usual line-spacing mechanism after each line is typed.

A paper apron is provided, the upper end by the frame 11, rearwardly against the tension of a return spring 17 said slide having pivotally mounted thereon a hue-space pawl 18 engaging with a ratchet wheel 20 secured to the platen shaft 10.

To assist in feeding the work-sheets 13,

'around the platen during the line-spacing operations, auxiliary front and back feedmoved upwardly when the finger-piece 24 is actuated to'draw on a connecting link 27 connected at its lower end to an arm 28 extending from a rock-shaft 30, to rotate the latter in suitable brackets 31, Fig. 4, extending downwardly from and rigidly secured to a rod 32, extending between the side or end plates 33 and 34 of said frame 11, and upon which the front and back feed-rolls 21 and 22 are pivotally mounted through the intermediary of L-shaped members 35 and 36, respectively. These L-shaped members have downwardly-projecting fingers 37 and 38, which engage with flat faces 40 and 41 of the rock-shaft 30, Figs. 3 and 4. When the rock-shaft is rotated to the position shown in Fig. 3, the fingers are spread to swing the members 35 and 36 about the rod 32 and against the return springs 23 to cast off the front and back feed-rolls.

A collating table 42 is pivotally mounted eccentric toand clear of the platen 9 and preferably on a rod 43 above the platen and carried by ears 44 and 45 extending up from cover plates 46 and 47, secured to the end lates 33 and 34 of the platen frame by suita le screws. These cover plates may be similar to those used in the Underwood machine, except that they have the cars 44 and 45 formed thereon and are made of heavier material. 7

The collating table 42 comprises a back 48 and two sides 50 and 51, and normally occupies the position at the introductory side of the platen shown at Fig. 2, where the side 50 rests a ainst a stop pin 52 projecting from the end 33 of the platen frame to hold the table nearly vertical. The collating table may be swung forwardly to. a substantially horizontal position shown in Figs. 1 and 3, so that the sheets may be adjusted and assembled thereon. It may be held in this position by a stop in 53 projecting from the side 51 of the col ating table, said pin engaging on the upper side of the end plate 34. In order to assemble the work-sheets on the collating table 42, two flaps 54 are first swung up out of the way about suitable hinges 55 on the collating table. The worksheets are then adjusted lengthwise of the collating table and relatively to each other according to indices or scales 56 on said table, andindices 57 which may be printed on the work-sheets. To assist in positioning the work-sheets crosswise ofthe collating table, there may be provided suitable side gaging means shown as comprising a lurality of pins 58 adjustable crosswise of t e collating table in holes 60. These pins are shown only on the left-hand side of the collating table; it should be understood, however, that similar pins may also be provided at the other side. When thework-sheets have been adjusted relatively to each other, with suitable carbons therebetwe'en, the flaps 54 are swung v clu down to hold the work-sheets against the table. The collating table 42 is swung from its collating osition or sheet-receiving position to its s eet-delivering position at the introductory side of the platen, as shown in Fig. 2. The work-sheets are then advanced therefrom and introduced around the platen by a paper-feeding unit comprising feedrolls 61, on said flaps and feed-rolls 62, on a shaft 63 supported on the side plates 50 and 51 of the collatin table 42, said shaft 63 havin a finger-wl ieel 64 preferably at the rightand side thereof b which the feedrolls may be rotated, and t us feed the worksheets 13 from the collating table down to and around the platen. It will be seen that the operator may by manipulating these feed-rolls adjust the work-sheets to bring the desired writing line accurately to the printing point by alining the line with the usual Wing-scales 65 arranged at the front of the platen as in the Underwood typewriting machine.

It should be understood that while the work-sheets are being introduced around the platen by the feeding unit on the collating table 42, the auxiliary or platen feed-rolls 21 and 22 are in their released position. To make certain that the path of the worksheets is clear as they are introduced around theplaten, the auxillary feed-rolls 21 and 22 are automatically released when the collating table is swung forwardly to its collating position in Fig. 3. During the latter part of the forward swinging movement of said collating table, a pin 66 projecting from the side 50 of said table engages with an arm 67 extending upwardly from the shaft 25, upon which the feed-roll release handle 24 is mounted. This arm is swung forwardly to cause the arm 26 projecting rearwardly from said shaft to release the feed-rolls 20 and 21, as hereinbefore described.

After the work-sheets have been introduced around the platen and adjusted relatively to the scale 65 at the front of the platen, the operator manipulates the feed-. roll release handle 24 to render the auxiliary feed rolls 21 and 22 effective, so that the work-sheets may be fed forwardly around the laten b the line-spacing mechanism ind ing the line-space handle 15.

To have the flaps 54 light and as strong as possible, each flap comprises a body portion 70 which is hinged to the collating table at 55, and which is provided with bent-up cars '71 to support the feed roll 61. Detachably secured to said body portion is a guide wire 72 which is reduced at its ends 73 to enter turned-up receptacles 74, Fig. 1, on the body .portion 7 O of the flap 54, the wire guide 72 being additionally held on the bod portion by spring fingers 75 onsaid flap. t will be seen that the fla s 54 are interdigitated to cover the back 0 the collating table, so that when the collatingtable is in its sheet-deliv-- ering position, Flg. 2, the flaps are effective to prevent the upper ends of the work-sheets guide wire. The guide wires 7 2 are alike in construction and either one may be attached to either flap.

To hold the flaps 54 in their effective or ineffective positions, each one is provided with a spring 80 which engages with a bentoff' portion 81 on the body of the flap, the bent-off portion engaging in a depression 82 of said spring when the flap is moved away from the collating table, as shown in Fig. 5. When the flap is moved down to its effective position, however, thebent-ofi' portion 81 of the flap engages with the upper end or incline 83 of the spring 8Q to press the feed-roll 61 against the coiiperating feedroll 62 on the collating table. It should be understood that the springs 80 may be located at any place lengthwise of the fla and 'may be located nearer to the feed-r0 ls if found desirable.

To avoid any possible difficulty which might be otherwise experienced by worksheets when-the table is swun to the sheetdelivering position and especially when the work-sheets project .a considerable distance beyond the edge of the collating table, there is provided at the upper end of the paper apron 12 a curved extension or guard 84, which guides the ends of the. work-sheets downwardly toward the platen, while they arebein adjusted on the collating table, as seen in ig. 1. The guard 84 may be rendered ineffective,

so that work-sheets may be inserted at the introductory side of the platen and in back of the collating table, thereby permitting the machine to be used independently of the collating table. To do this, the curved guard 84 of the paper apron may be detachably supported on the table by fingers 85 and 86 engaging onthe front and the back of the paper table.

From the foregoing description, it will be understood that two paper-feeding units are provided, that one of said paper-feeding units is preferably supported on the collating table and is effective to feed the worksheets to a second paper-feeding unit, the latter including the platen, and that the latter paper-feedin unit is effective to feed the work-sheets a ter they have been adjusted around the platen by the paper-feeding unit carried by the collating table. It

should also beiunderstood that the device may be used to feed individual work-sheets into the machine, especially when it is desired to have the sheets squared with the platen and-alined with a particular scale marked crosswise of the platen, the side gage being provided on the paper table for this tion for the purpose of adjusting worksheets thereon. v e
